They passed out by the big gate and caught sight of the brown dwarf on the parapet of the stockade.
At the first collision we saw a big ant fall upon a brown dwarf, and annihilate it at one blow.
On the parapet, in his old place, the brown dwarf squatted, expressionless as the Sphinx.
|brown dwarf |
A celestial body with insufficient mass to sustain the nuclear fusion that produces radiant energy in normal stars. It is believed that a brown dwarf is formed with enough mass to start nuclear fusion in its core, but without enough for the fusion to become self-sustaining. Theory suggests that a body with about one percent of the mass of the Sun—or ten times the mass of Jupiter—can generate this initial fusion, but that it needs at least eight percent of the Sun's mass to sustain the fusion. After the fusion ends, the dwarf still glows for a period from radiating heat, with a surface temperature of about 2,500°K (4,532°F) or less. See Note at dwarf star.
